Shrub rose plant named ‘Poultc007’

ABSTRACT

A new garden rose plant of the shrub class which has abundant, yellow flowers and attractive, dark green, glossy foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical classification: Rosa hybrida.

Variety denomination: ‘Poultc007’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of gardenrose plant which originated from a controlled crossing between thefemale seed parent plant, an unnamed seedling, and the male pollenparent plant, an unnamed seedling. The two parents were crossed duringthe summer of 1997, and the resulting seeds were planted in a controlledenvironment in Fredensborg, Denmark. The new variety is named‘Poultc007’.

The new variety may be distinguished from the female parent, by thefollowing combination of characteristics:

-   -   1. ‘Poultc007’ has a low growth height of 40 to 60 cm while the        female parent plant has a medium growth height of 60 to 100 cm.    -   2. ‘Poultc007’ exhibits flowers with a smaller diameter than        those of the unnamed female parent.    -   3. ‘Poulc007’ develops flower buds in greater quantity per        flowering stem than the female parent plant.

The new variety may be distinguished from its pollen parent by thefollowing combination of characteristics:

-   -   1. The pollen parent has a light yellow flower color, while        ‘Poultc007’ has medium yellow flower color.    -   2. Open flowers of the pollen parent are 32 mm in diameter while        flowers of ‘Poultc007’ are 60 mm in diameter.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

-   -   1. Uniform and abundant yellow flowers;    -   2. Vigorous, but compact growth when propagated both as a budded        rose and on its own roots;    -   3. Disease resistance;    -   4. Dark green attractive foliage;    -   5. Suitability for growth in a container.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventors, anddistinguish ‘Poultc007’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 1997 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark.

‘Poultc007’ was selected in the spring 1998 by the inventor as a singleplant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poultc007’ by traditional budding and rootedcuttings was first done by Mogens N. Olesen in his nursery inFredensborg, Denmark in July, 1998. This initial and other subsequentasexual propagations conducted in controlled environments havedemonstrated that the characteristics of ‘Poultc007’ are true to typeand are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poultc007’, as observed in its growthin a field nursery in Jackson County, Oreg. Observed plants are 2 yearsof age, grown on Rosa multiflora understock. Color references are madeusing The Royal Horticultural Society (London, England) Color Chartpublished in 2001, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety‘Poulgode’, a rose variety from the same inventors described andillustrated in U.S. Plant patent application Ser.
